SiPECIFICATION formingpart of Letters Patent No. 466,485,dated January 5, 1892. Application filed February 11, 1891. Serial No. 381,053; (No model.)

In said drawings, a indicates the mouth- The method employed in uniting the parts 40 piece of the bit, which may be covered with is illustrated in Fig. 4, in which the cheekrubber' or other covering material or be of piece is shown to be cast in a bent position or naked metal, and may be either rigid or of form, so that the parts 6 6 lie at angles with jointed sections in any ordinary manner. At one another, and the head can be readily the ends of said mouth-piece are verticallyplaced in position on one of them,after which 5 45 perforated heads a, adapted to receive the the other of said parts e is bent into line, the pivotal portions 6 of the rein-loop bars at of said other part passing into the opposite end the cheek-pieces b, the said pivotal portion e of the pin-perforation. When a separate key extending diametrically across the rein-ring is employed with its key-hole, the cheek-piece c, as will be understood. The pivoted portion being straightened, as shown in Fig. 4, the two 50 or pin e is in two parts, as shown in Fig. 3, portions ebeing thus broughtinto line, so that both being integral with the ring 0, as shown, the head can be slipped on said portions and the hole a be brought into coincidence with the openingf, the key h can then be driven home and the bit be made complete so far as the metal parts are concerned.

5 \Vhile the mouth-piece maybe bare metal, I prefer in finishing the said mouth-piece to cast a rubber covering around the same, and

in doing so I prefer to employ dies or molds adapted to give the desired form to the rubber.

Having thus described the invention, what I claim as new is- 1. The improved bridle-bit, combining with the mouth-piece having keys or inner bearin gs within the heads thereof cheek-pieces having pivotal pins 9 6 arranged on opposite sides of said innerbearin gs and havinga limited play at right angles to the axis of the mouth-piece substantially as and for the purposes set forth.

2. The improved bridle-bitherein described, in which is combined a mouth-piece open at opposite sides to allow the insertion of the pivotal pins or sections of the cheek-pieces and provided with key-holes 0,, extending at right angles to the longitudinal centers of said pins, cheek-pieces having pivotal sections or pins separate from one another at the longitudinal axial center of the mouthpiece to admit of the pins being inserted in the mouth-piece openings from opposite sides, and a key or pin secured in said key-hole a and extending into the place of separation between said pins and limiting or stopping the vertical movement of said pins, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 10th day of February, 1891.

GEORGE BROOKINGTON.
